Abstract
Honeycomb structures of hexagonal arrays are naturally occurring structures that occur in many organisms, such as the venation of a leaf (Liu, H., Zou, M., Wang, D., Yang, S. & Liang, M., 2014). This special structure is vital in various applications. Specifically for venation, it is the optimal support structure for the leaf and distributes the veins equally throughout it. The purpose of this experiment was to test a honeycomb’s structural integrity by using a Structural Stress Analyzer. Young’s modulus of each structure was analyzed with phone cases. A simple iPhone 6 Plus case was chosen from a variety of pre-designed cases online and then printed using the 3-D printer, Z-18, from Makerbot. Two settings were used when printing: no infill and 15% infill. Since the printer automatically infills an object with a hexagonal structure, the 15% infill provided as the honeycomb structure and the 0% infill served as the control. The hypothesis of the control group having a Young’s modulus less than the phone cases with honeycomb structures was supported. At α = 0.10, the Young’s modulus in cases with 15% infill was significantly larger than the control, t (3) = -1.66, p = 0.086. In conclusion, the idea of implementing biomimicry in everyday inventions or innovations are beneficial and efficient.
